LMs: Understanding Code Syntax and Semantics for Code Analysis

no code implementations20 May 2023 Wei Ma, Shangqing Liu, ZhiHao Lin, Wenhan Wang, Qiang Hu, Ye Liu, Cen Zhang, Liming Nie, Li Li, Yang Liu

We break down the abilities needed for artificial intelligence~(AI) models to address SE tasks related to code analysis into three categories: 1) syntax understanding, 2) static behavior understanding, and 3) dynamic behavior understanding.

Learning Program Representations with a Tree-Structured Transformer

Learning to Represent Programs with Heterogeneous Graphs

no code implementations8 Dec 2020 Kechi Zhang, Wenhan Wang, Huangzhao Zhang, Ge Li, Zhi Jin

To address the information of node and edge types, we bring the idea of heterogeneous graphs to learning on source code and present a new formula of building heterogeneous program graphs from ASTs with additional type information for nodes and edges.
